Bello has filed House Resolution 2103 calling for Marquez's removal from office.

Bello, in a press statement, said Marquez caused pubic anger by failing to separate the interests of impeached Chief Justice Renato Corona and the Supreme Court.

He said Marquez should step down "to prevent the further erosion of the people's trust in the highest court of the land."

"We are pulling all stops to prevent Mr. Marquez from escaping accountability for his abuse of office," he added.

He mentioned Section 3 of Presidential Decree 842, as amended, that describes the qualifications, appointment and tenure of the members of the Office of the Court Administrator in the Supreme Court.

The decree states that "The Court Administrator and the Deputy Court Administrators may be removed or relieved for just cause by a vote of not less than eight (8) Justices of the Supreme Court."

Bello said the way Marquez has been defending himself puts the credibility of the Supreme Court at risk.

"Here you have the administrator of the High Court that has turned himself into a private lawyer for impeached Chief Justice Renato Corona, using his public position and public funds for this purpose. And the same person also used the court’s funds for ineligible expenses," he said.

"This is a double whammy for the Supreme Court’s credibility and integrity," he added.

"Marquez has said that the Ombudsman has no authority over his actions. This defiance of the Constitution is unacceptable, and we ask the Supreme Court to uphold the charter by dismissing him," Bello said.
